Remarks

10 Oct 2011: Based on 10 RV data, Norris er al. (2011) "exclude the presence of almost any substellar companion with P < 28 days and Msin i > ~ 1 Mjup."
24 Jan 2011: Based on 26 high resolution spectra over 55 days, Jacobs et al. (2011) "rule out any RV variations with amplitudes higher than 0.79 km/s on periods shorter than 50 days."
